Building Bridges with Iran

Since the Iranian revolution in 1979 no US president has ever met, or spoken, directly to any Iranian president. But there is suddenly the prospect that President Obama maybe about to meet the new Iranian President Hassan Rouhani. It is just a maybe - but both leaders are at the UN General Assembly. And unlike his predecessors, Mr Rouhani is seen as something of a moderate, who has been making friendly noises towards the US lately. So could this ultimately lead to an easing of sanctions?
